Duo Enrollment Guide

Duo's self-enrollment process makes it easy to register your phone or tablet and activate the Duo Mobile application so you can receive Duo requests via push notification and tap to approve and login.

Enrolling Your Phone or Tablet in Duo

Duo prompts you to enroll the first time you log into into a protected VPN or web application when using a browser or client application that shows the interactive Duo web-based prompt. Alternatively, you might receive an email from your organization's Duo administrator with an enrollment link.

Supported BrowsersChromeFirefox, Safari, Edge, Opera, and Internet Explorer 8 or later. Some browsers do not support all of Duo's authentication devices (for example, Security Keys won't work with Internet Explorer). For the widest compatibility with Duo's authentication methods, we recommend recent versions of Chrome and Firefox.

Step One: Welcome Screen

Proceed to http://identity.sfasu.edu, enter your mySFA username and password and then click Start setup to begin enrolling your device.

Begin Enrollment

Step Two: Choose Your Authentication Device Type

Select the type of device you'd like to enroll and click Continue. We recommend using a smartphone for the best experience, but you can also enroll a landline telephone, a security key, or iOS/Android tablets.

Select Device Type

Step Three: Type Your Phone Number

Select your country from the drop-down list and type your phone number. Use the number of your smartphone, landline, or cell phone that you'll have with you when you're logging in to a Duo-protected service. You can enter an extension if you chose "Landline" in the previous step.

Double-check that you entered it correctly, check the box, and click Continue.

Enter and Confirm Phone Number

If you're enrolling a tablet you aren't prompted to enter a phone number.

Step Four: Choose Platform

Choose your device's operating system and click Continue.

Step Five: Install Duo Mobile

Why use Duo Mobile?

  • It's fast & easy
  • Works in any country
  • Doesn't require cell service

Duo Mobile is an app that runs on your smartphone and helps you authenticate quickly and easily. Without it you'll still be able to log in using a phone call or text message, but for the best experience we recommend that you use Duo Mobile.

Follow the platform-specific instructions on the screen to install Duo Mobile. After installing our app return to the enrollment window and click I have Duo Mobile installed.

Install Duo Mobile

Step Six: Activate Duo Mobile

Activating the app links it to your account so you can use it for authentication.

On iPhone, Android, and Windows Phone activate Duo Mobile by scanning the barcode with the app's built-in barcode scanner. Follow the platform specific instructions for your device:

Scan Barcode to Activate

The "Continue" button is clickable after you scan the barcode successfully.

Activation Success

Can't scan the barcode? Click Or, have an activation link emailed to you instead. and follow the instructions.

Step Seven: Configure Device Options (optional)

You can use Device Options to give your phone a more descriptive name, or you can click Add another device to start the enrollment process again and add a second phone or another authenticator.

If this is the device you'll use most often with Duo then you may want to enable automatic push requests by changing the When I log in: option and changing the setting from "Ask me to choose an authentication method" to "Automatically send this device a Duo Push" or "Automatically call this device" and click Save. With one of the automatic options enabled Duo automatically sends an authentication request via push notification to the Duo Mobile app on your smartphone or a phone call to your device (depending on your selection).

Automatic Device Options


Click Continue to login to proceed to the Duo Prompt.

Learn more about other types of devices you can enroll, like Security Keys and macOS Touch ID, or different ways of using your phone to authenticate, like with receiving SMS passcodes or approving logins via phone call. Some authentication methods may be restricted by SFA policy, or incompatible with some browsers or applications.
